I’ve been working with Hatim and his Siya Tech team to build our children’s secondhand marketplace app KiDSiE. Hatim has been an instrumental partner in building KiDSiE from the ground up/idea inception. He has gone beyond the technology remit providing meaningful feedback and helpful guidance on overall business strategy, commercials, company documents and presents relevant opportunities as they arise. He and his team are dedicated, responsive, thoughtful and professional. I look forward to continuing to develop, grow and scale KiDSiE with both Hatim and his team!
